GM’s Electric Vehicle Sales Fell Off A Cliff Last Quarter

General Motors' joint venture Ultium Cells will produce cheaper, high-energy-density lithium-manganese-rich (LMR) batteries in Tennessee. The LMR batteries, with 65% manganese and 35% nickel, will be used in full-size trucks and SUVs, offering up to 400 miles of range. GM is the second-largest EV seller in the U.S. The $1 billion factory expansion is expected to be completed by 2028, adding 500 jobs.

GM will end light-duty Silverado 1500 production in Oshawa, Ontario, in November, replacing it with GMC Sierra HD by 2028. The $144M investment follows labor talks, maintaining current employment levels. The plant currently produces Silverado models, with 2026 output expected at 114,000 trucks. GM also invested $215M in its St. Catharines propulsion plant. U.S. tariffs on Canadian-made cars are impacting Ontario's auto sector.

Ultium Cells, a GM-LG Energy Solution joint venture, is investing $1 billion to upgrade its Spring Hill battery plant for next-gen EV cells. The 2028 project will create 500 jobs and focus on prismatic LMR batteries, aiming to reduce costs and improve performance. This follows prior investments of over $2 billion at the site.

GM faces a class action lawsuit over alleged defects in the continuously variable transmission (CVT) of certain Chevrolet and GMC vehicles, including the Chevy Malibu, Trailblazer, Equinox, and GMC Terrain. The complaint claims the defects cause slipping, hesitation, and loss of propulsion, posing safety risks. GM is accused of knowing about the issues since 2021 and failing to address them effectively. The lawsuit also alleges improper handling of warranty claims.

General Motors (GM) and LG Energy Solution plan to mass-produce lithium manganese-rich (LMR) prismatic battery cells at their Spring Hill, Tennessee plant by 2028. The $1 billion investment aims to lower EV costs using manganese. GM expects to hire 500 new workers, with the plant also producing stationary storage batteries. The company targets electric trucks and large SUVs for LMR batteries, aiming for a range over 400 miles.

GM's U.S. EV sales dropped 61.7% YoY in Q3 2026 to 25,473 units, accounting for 3.8% of total sales. Overall sales fell 5.5%, with GM citing a smaller EV market. Cadillac's EVs performed relatively better, while models like Equinox EV saw steep declines. Ford also reported an 80% YoY EV sales drop.
